My guess would be that in order for this technology to be scaled-up to classroom size (from say, boardroom-size) with sufficient clarity to be truly and comfortably interactive would be inordinately expensive, especially for Tech's budget. OK, blast away at my failure to keep up!
I performed a product presentation for one of the Worley Parsons Groups recently where we used this technology. I was physically on the west side of Houston with about 35 engineers while we were being 'broadcasted' to 2 other Houston offices, 1 in the UK and 1 on the west coast of the USA simultaniously (there were a total of 66 engineers effectively watching at one time). They could see me and the presentation slides on their screens and during a question, their group came up on my screen so it was almost total interaction and responses as if we were all in the same room.
I am sure the set-up was an expensive investment, but the overall savings (especially to a company like mine) was invaluble. For me to have done that for all those engineers while at the same time, the time aways from their 'billing time' in each office more than paid for the system, I am sure.
My son was teaching classes at Asbury Seminary in Wilmore Ky at least 8 years ago that were simultaneously presented at their campus in Florida. As memory serves the classes were fully interactive. Asbury had made a significant investment for the technology but like so many things involving technology, its probably less expensive now than it was then.
I completed my MBA from Liberty University's distance learning. We had closed book tests that were administered by a proxy that signed and confirmed as such. The proxy was my manager.
In comparing experiences with those in traditional MBA programs and EMBA programs, the amount of research and writing I did was much greater.
CHC,
I was looking int o the online MBA from Liberty as well. What was your experience like with that? Ran into anything else that sounded better?
Test can be administered through a myriad of ways. Like CHC said via a proxy which is the more traditional approach and probably the cheapest. Open book as well...but what I have found, those can be the most difficult. Another way, taking a test in a Facilitator Monitored testing center with dedicated computers and the student logs onto the computer (either a website or CBT module) and from a menu selects the appropriate test. But those are usually limited to the multiple guess, true/false, matching, labeling, or fill in the blank type assessments. But the nice thing about this type of testing, the student knows how well or bad they did on the exam before they get up out of their chair. As an instructor, I like this type of testing because I don't have to spend countless hours grading tests. Additionally, the Access or SQL database that this type of testing is designed around, gathers all of my data and I can build reports and identify trends analysis over a broader range of students/time without having to pull out my slide rule.
